Dragons will no doubt win the race, Souths will be next across the line and the 'Dogs could crack 10k with another good initiative between now and season's start.
That said, and this isn't a crack at Saints because I'm actually a member of them... they do have two regions to pull from and I'm quite certain the 6-game memberships are all counted as part of those stats. While those 6gamers aren't the majority, they do make up a fair amount of the memberships and that in itself is a massive advantage to have. The home game split is half-half this year too which has possibly been well received, especially at Kogarah, where they'll get all the back-end games of the season which should all be quality contests.
